The end of the spring 406 away from the blister box cover 3 is fixedly connected with a rectangular clamping block 405, which is connected to the blister box cover 3 and the blister box shell body 1 by clamping, so that it is convenient to fix. The rectangular clamping block 405 is slidably inserted in the second groove 13, and the rectangular clamping block 405 is conveniently connected to the limit block 404 by clamping through the second groove 13. Symmetrically distributed first grooves 10 are provided at both ends of the blister box cover 3, and a clamping plate 7 is rotatably installed inside the first groove 10. Symmetrically distributed fixed clamping blocks 6 are provided on both sides of the blister box shell body 1. The end of the clamping plate 7 away from the blister box cover 3 is rotatably clamped at the lower end of the fixed clamping block 6, so that the blister box cover 3 and the blister box shell body 1 are fixed for the second time. An anti-skid pad 14 is fixedly installed on the lower surface of the blister box shell body 1, and the anti-skid pad 14 increases the anti-skid property of the blister box.

[0020] A first sealing ring 11 is fixedly installed on the lower surface of the blister box cover 3, a second sealing ring 12 is fixedly installed on the lower surface of the blister box cover 3, and symmetrically distributed fixing blocks 9 are fixedly installed on the side of the blister box shell body 1, and an insertion rod 501 is fixedly provided on one end of the fixing block 9 away from the blister box shell body 1, and symmetrically distributed handles 8 are provided on both sides of the blister box shell body 1, and a socket 502 is opened at the top of the handle 8. One end of the insertion rod 501 is movably inserted into the socket 502 at the top of the handle 8, so that the sealing of the box body is enhanced by the sealing ring, and the handle 8 is convenient for taking the blister box.

[0021] Working principle: First, when using the blister box, the user first rotates the card plates 7 on both sides of the box body that are stuck on the fixed card blocks 6 to disengage the card plates 7 from the fixed card blocks 6, and then presses the pressing block 401, so that the extrusion plate 402 squeezes the first spring 403. When the first spring 403 moves, it pushes the limit block 404 to move, so that the rectangular card block 405 is disengaged from the stuck position of the limit block 404. At the same time, the second spring 406 automatically drives the rectangular card block 405 to retract due to the elastic force, and then moves the blister box cover 3 to the side, puts the objects to be stored into the box body, and then moves the blister box cover 3 to the top of the box body, aligns the groove between the first sealing ring 11 and the second sealing ring 12 with the protrusion at the top of the blister box shell body 1, and then presses the blister box cover 3 downward to the blister box shell body 1, so that the lower end of the first sealing ring 11 is tightly connected with the arc at the top of the blister box shell body 1, and the second sealing ring 12 is pressed downward to the blister box shell body 1, The lower end of the sealing ring 12 is inserted into the box body, and the double-layer sealing makes the sealing effect better and reduces heat loss. While the blister box cover 3 is pressed, the rectangular block 405 is inserted into the second groove 13 and connected with the limit block 404. Then the card plate 7 is rotated to make it clamped on the fixed block 6 on the blister box shell body 1, so that the blister box cover 3 is firmly connected to the box body. Because there is a vacuum chamber between the blister box shell body 1 and the blister box inner box body 2, the blister box has a certain thermal insulation effect. At the same time, in order to prevent the internal heat of the blister box from accumulating in the vacuum chamber, part of the heat is transferred to the blister box shell body 1, and the handle 8 is used to move and take it to prevent scalding of the user. When the blister box is placed in the appropriate position, the anti-skid pad 14 at the bottom of the blister box increases the friction between the blister box and the placement platform, making the blister box more stable when placed. Finally, the blister box can be opened and closed according to the original operation.

[0022] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
